One of three mild profanities invented at Dullen Studios© for the inhabitants of the Lost Lands in their first indie film, The Lost Ones. Its use has now broadened, and is commonly used in this general area.
The first element (gizzem-) is almost certainly a corruption of goddamn
. The second half (-blutz) was probably influenced by fuck
. The word is clearly styled to look as if it is of Yiddish descent.
"Gizzemblutz!" Gordon grumbled as he stubbed his toe on his way in from the garage.
